Spyder batteries are in my opinion one of the best battery for the dollar on the market. They don't puff and give continued high performance. The staff at Progressive R/C are the greatest. They are what customer satisfaction is all about.

used it about 4 times charged it to half and put it aside for two weeks after i got back from a vacation got low vol message on icharger

ProgressiveRC Comment: Sorry for the troubles, and we'd be happy to address this issue. It certainly sounds like something else is at play here, LiPo batteries (regardless of brand) will hold voltage over the course of a few days/weeks. We've had no reports of this issue with any of the Spyder batteries and warranty everything we offer for peace of mind.
